Development of a complete model of turbulence revisited

The primary technical objective of this research project has been to develop and test a new set of constitutive equations suitable for general engineering applications. In accomplishing this objective, particular emphasis has been focused upon predicting rates of departure from and return to equilibrium. Throughout the research in this project, a secondary goal has been to devise turbulence model equations subject to the self imposed constraints that the resulting equations pose no special difficulties for conventional numerical procedures, and, to the greatest extent possible, reflect much more of the physics of turbulence than previously attempted in an engineering model.
